ZCHKAB is the test program for the COMPLEX*16 LAPACK
 ZCGESV/ZCPOSV routine
 The program must be driven by a short data file. The first 5 records
 specify problem dimensions and program options using list-directed
 input. The remaining lines specify the LAPACK test paths and the
 number of matrix types to use in testing.  An annotated example of a
 data file can be obtained by deleting the first 3 characters from the
 following 9 lines:
 Data file for testing COMPLEX*16 LAPACK ZCGESV
 7                      Number of values of M
 0 1 2 3 5 10 16        Values of M (row dimension)
 1                      Number of values of NRHS
 2                      Values of NRHS (number of right hand sides)
 20.0                   Threshold value of test ratio
 T                      Put T to test the LAPACK routine
 T                      Put T to test the error exits
 DGE    11              List types on next line if 0 < NTYPES < 11
 DPO    9               List types on next line if 0 < NTYPES <  9

  MAXRHS  INTEGER
          The maximum number of right hand sides
  NIN     INTEGER
          The unit number for input
